The maximum recommended amount is half the maximum supported amount, so you not only have more swap than recommended, you have more swap than the kernel can actually use (467488 * 2 = 934976 pages) and should consider either increasing kern.maxswzone so the kernel can use all of the swap you've configured (at the cost of slightly reducing usasble physical memory) or decreasing the amount of swap.
